MAX-DOAS measurements of atmospheric trace gases in Ny-Ålesund [PDF]

, 2003
Abstract. A new approach to derive tropospheric concentrations of some atmospheric trace gases from ground-based UV/vis measurements is described. The instrument, referred to as the MAX-DOAS, is based on the well-known UV/vis instruments, which use the sunlight scattered in the zenith sky as the light source and the method of Differential Optical ...

Retrieving tropospheric nitrogen dioxide from the Ozone Monitoring Instrument: effects of aerosols, surface reflectance anisotropy, and vertical profile of nitrogen dioxide [PDF]

Atmospheric Chemistry and Physics, 2014
Retrievals of tropospheric nitrogen dioxide (NO2) from the Ozone Monitoring Instrument (OMI) are subject to errors in the treatments of aerosols, surface reflectance anisotropy, and vertical profile of NO2.

Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

Advanced Intelligent Discovery, EarlyView.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...

Retrievals of formaldehyde from ground-based FTIR and MAX-DOAS observations at the Jungfraujoch station and comparisons with GEOS-Chem and IMAGES model simulations [PDF]

Atmospheric Measurement Techniques, 2015
As an ubiquitous product of the oxidation of many volatile organic compounds (VOCs), formaldehyde (HCHO) plays a key role as a short-lived and reactive intermediate in the atmospheric photo-oxidation pathways leading to the formation of

Bio‐guided fractionation of (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid from Abelmoschus sagittifolius root as a potent α‐glucosidase inhibitor: An integrated in vitro and in silico study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Abelmoschus sagittifolius stands out as a valuable medicinal source for developing functional food targeting type 2 diabetes. This study investigated the α‐glucosidase inhibitory potential of an active fraction obtained from A. sagittifolius roots (ASR), enriched in (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid (OA), using both enzyme ...

Regulating Solvent Co‐Intercalation in Bi‐Layered Vanadium Oxides for Zinc Batteries by Nanoconfinement Chemistry

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
The feasibility of regulating solvent co‐intercalation by electrode nanoconfinement design is demonstrated. Through decreasing interlayer hydration and introducing organic molecules with reduced lone electron‐pair density, the interlayer solvo‐philicity of bi‐layered vanadium oxides is tuned.
